production of a proof material,

Patented Jan. 1, 1935 UNITED STATES- PATENT OFFICE f s (c1. zoo-56) My invention relates to improvements in miniature packets, and more particularly to those packets adapted to contain coloring material to be intermixed with a food product or the like in coloring the latter to the desired tint or shade.

for use. 7

Among the objectsof my invention are the production of such packets that will be neat and attractive in appearance, convenient to use, economical to make, and satisfactory and eillcient for I use wherever found-applicable. I Other objects of my invention are the provision of a packet that will be substantially moisture-proof and air-proof, of minimum weight, substantially flat so that the same may be mailed without special packing and otherwise handled, and transparent whereby the user may easily ascertain when it has been completely emptied. A further object of my invention is theproduction of a packet of the kind described, in which the packet shall be of a plurality of super-. imposed sheets cut to a polygonal outline so as to prevent waste of material in cutting and to obtain a maximum of sealing area about the material being packaged.

An additional object of the invention is the packet of the kind'described, which shall have a cover sheet of a pliant, transparent, and substantially air-proof and moistureand a reinforcing sheet of a sturdier or more rigid material and preferably cheaper, superimposed thereon, so that the packet will be form-sustaining and not too flimsy and thus be better able to withstand the usage to which it may be put.

Still further objects of my invention are the provision of a packet of the kind described, which shall be of flat, polygonal shapereadily handled in the cutting, filling and sealing operations through automatic machinery, and which may be easily torn and emptied by the ultimate user.

Many other objects and advantages of the invention herein shown and described will be obvious to those skilled in the art. to which this invention appertains, from the disclosures herein given. I

To this end, my invention consists in the novel construction, combination and arrangement of parts, and the method of obtaining the same, herein shown and described, and more particularly pointed out in the claims.

of such individual packets, taken substantiallyalong the line 3-3 of Fig. 2-.

- Referring more particularly. the drawing,

wherein I have illustrated one of thepreferred embodiments or my invention, A' represents one 10 of the miniature, individual packets as it'appears ready for use, and is preferably of 'i'iat shape with .a shallow pocket 1 having a small quantity of coloring: matter 2 therein, as for instance a powdered compound of yellow AB orlOB dye with a suitable diluent or carrier therefor, the quantity varying with the particular purpose intended.

This pocket ,may be circulariin shape, but the packet itself 'is preferably'of'a polygonal'shape,

gas for example, the hexagon form shown, this hexagon shape adapting itself well tofhandllng in automatic machinery, and yith no waste of material, the sides of the hexagon being indi cated at 3.

The packet A may be formed. of asheetof' 26 tively pliant or flimsy materia'lwhich is substan-' tially air-proof and moisture-proof and 'transparent, such as regeneratedcellulose, as cellophane or the like 4, superimposed upon a relatively cheaper, stiffer and sturdier material, such as the paper sheet 5. The reinforcing sheet may preferably be made opaque in order that it shall forma good background for colored material that o may be placed in the packet. The transparent, pliable sheet 4 and the reinforcing sheet 5 are sealed togetherv completely aboutijtheir marginal areas bounding the pocket 1, as at 6, and it is to be particularly stressed at this time that the hexagon shape-of packet will give a maximum of sealing areaabout the pocket with a minimum of waste of paper out from the blank sheet, and

uniform in width about the periphery.

If desired, a second sheet of material I, similar to the sheet 4, may be superimposed on the other side of the reinforoing'sheet, similarlyto the sheet 4, and in which ,case the'reinforcing sheet need not be of a moisture-proof and airproof materijl, but yet the resultant packet as a whole will have the desired weather-proof prop erties. The secondsheet 7 may be sealed to the reinforcing sheet about the opposed marginal areas similar to the width of the sealed area 6. The packet is preferably substantially flat so 1.

that it may-beplaced within an-ordinary mailing the sealing area about the pocket will be nearly Further, the packet 'tically no stretch,

envelope, or otherwise handled, and has the shallow and slightly bulged pocket centrally between the sealed marginal edge, and is weather-impervious. Further, the packet will be form-sustaining even 'though the cover sheet is of a relatively pliant and flimsy material. The packet is regular in shape and may be easily emptied, the slight bulge of the pocket aiding in this step. is attractive in appearance, is easily identified by the purchasers, and is easy to ascertain complete emptying. The composite packet is much more readily torn and therefore more easily emptied than if it did not have the sheet 5 as part thereof, as such sheet has pracwhile the regenerated cellulose sheet. or sheets alone are relatively difllcult to tear across, as may be easily demonstrated by test.

These packets, although intended principally for the packaging of food coloring matter, and the like, are also adapted to the packaging of other commodities, especially where small quantities of material are to be so packaged, as for example samples and-even commercial sizes of commodities, where attractiveness of package, ease of handling and mailing, visibility of contents and protection from the atmosphere, easy tearing of' the packet for emptying the contents, are desired.

These packets may be formed by passing one of the sheets of flimsy material, or both of them, through suitable machinery (not shown), so as to preferably obtain. automatic handling and economy of operation. The reinforcing sheet of paper also preferably travels in the same direction as the more pliant cover sheets so as to be superimposed thereon or therebetween before its discharge from the machine. At some suitable stage of progress, individual portions of material 2 are introduced between one of the pliant sheets and the reinforcing sheet at intervals suitably spaced apart, and then the superimposed sheets are pressed together with suitable adhesive, preferablydry, or other sealing material therebetween, was to seal completely about the pockets of material. When dry adhesive is used, heat may be applied atthe time of pressure of the sheets toward one another, to thereby soften the adhesive. The bulge for the pockets are formed in any suitable manner during the progress of the sheets through the machinery, this bulge extending outwardly from the plane of the material of the bounding edges of the sheet or packet strip.

The sealed sheets having the terial deposited therebetween pockets of maand completely made therein; hence rangement, structure and sealed in place may then be formed into individual packets in any desired manner, as by cutting a single width of packet along the continuous length of the sealed sheets, with longi- Z -kag, toothed or serrated lines to form pairs of adjoining side edges 3-3 of the hexagon. Then, the individual packets are finally formed by severing transversely of the single serrated strips of packets, intermediate the pocketsvtherein, as along the dotted'lines shown in Fig. 1. No trimming of sheets is required, and hence no waste, and there will be a maximum of sealing area of substantially uniform width about the pocket of sealed material.

Having thus described my invention, it is obvious that various immaterial changes may be I do not wish to be understood as limiting myself .to the exact form, ar-

combination of parts claimed and described, except as limited by the state of the art tains, and the claims hereto appended.

What I claim as new and desire to secure by Letters Patent is:

l. A container consisting of a pair of regenerated cellulose sheets secured together, to provide a pocket therebetween adapted to receive to which this invention appera predetermined quantity of material; and a sheet of paper between said pair of sheets.

2. A container consisting of a pair of substantially moisture and air-proof-regenerated cellulose sheets secured together along their marginal edges and spaced apart adjacent the central portion to provide a material-receiving pocket thereat; and a sheet of paper between said sheets and secured thereto.

3. A container consisting of a reinforcing sheet; and a more p ant sheet of regenerated cellulose superimposed thereon and secured thereto at a marginal edge of the cellulose sheet, and whereby tearing through is facilitated. D

4. A container of the kind described, consisting of a pair of pliant sheets of regenerated cellulose and a paper sheet therebetween, and all of said sheets fixedly secured together along their.

bounding edges.

5. A container of the kind described, comprising a pliant regenerated cellulose sheet, and a stiffer reinforcing sheet having a portion spaced therefrom to form a material-receiving pocket therebetween, said sheets fixedly secured together at a bounding edge of the cellulose sheet to facilitate tearing through said bounding edge.
